It has always seemed to me that playoff success often requires playoff experience. This playoff experience needs to be acquired consistently enough to be a part of the complete team's mentality.
The team that wins the championships, I believe, are the ones that wanted it the most. This is the motivation that drives the players to find another, higher level within themselves.
Many Cowboys fans today do not know what it feels like to lose a conference championship or Super Bowl. Consoling yourself with the fact that they went deep in the playoffs doesn't work until many years down the road.
Sometimes it only takes one or two playoff game losses for players and teams to understand what needs to be done during these rare opportunities.
Part of the reason the Cowboys won Super Bowl 6 was because they lost Super Bowl 5....in addition to two losses in NFL championship games prior to Super Bowls. They had to feel the pain. They won Super Bowl 6 because they refused to be denied. That is the mentality that is required.
There is no fear, no doubt, no excuses. They win because they just got to. When that opportunity arrives, there are no vacations in Cabo, interviews on TV shows, other pursuits of interest. The players that respect the opportunity will leave nothing back, they will give everything they are capable of giving. They never want to consider in the many following years, whether their lack of commitment was the deciding factor in a loss.
Even the team of the 90's went through an embarrassing loss in 1991 to the Lions by beating themselves with 4 turnovers.
Obviously, there are exceptions where a seemingly average team will rise from the ashes for a season and dominate. However, the general rule is that Super bowl champions had been winning for a few seasons or more until they were able to come together and put together a Super Bowl season.
